Description

technical field [0001] The present invention relates to a liquid crystal display panel (liquid crystal display panel, LCD panel), and in particular to a multi-domain horizontal alignment (MHA) liquid crystal display panel. Background technique [0002] Thin film transistor liquid crystal display has gradually become the mainstream of the market due to its superior characteristics such as high image quality, good space utilization efficiency, low power consumption, and no radiation. Currently, the performance requirements of the market for liquid crystal displays are towards high contrast (High Contrast Ratio), fast response and wide viewing angle. Currently, there are technologies capable of meeting the requirement of wide viewing angles, such as Multi-domain Vertical Alignment (MVA) TFT-LCDs, Multi-domain Horizontal Alignment (MHA) TFT-LCDs, and the like. [0003] FIG. 1 is a top view of an existing thin film transistor array substrate used in a multi-domain horizontal ali...
